“…The benefits of vertical greening include noise abatement (Van Renterghem et al 2013), filtering of airborne dust and pollutants (Ottele et al 2010, Sternberg et al 2010, and reduction of temperature close to the area of vertical greening (Onishi et al 2010, Wong et al 2010, Perini et al 2011a). The thermal aspects of vertical greening are, however, still under debate (Hunter et al 2014).…”

Vertical greening has attracted increasing interest during recent years as a way of maintaining areas of vegetation despite increased urban densification. Living wall systems are a novel form of vertical greening in the Scandinavian climate and there is a lack of scientific knowledge on their functioning. We have performed a full-scale field experiment in an industrial area in Malmö, south-western Sweden, to compare the qualityquality and coverage of 16 plant species in two systems used for vertical greening. We hypothesized and found that: (1) living wall systems with perennial plants are feasible in the Scandinavian climate, (2) the qualityquality of plants was better and (2) the area covered was greater in the Rockwool system than in the pumice-filled pocket system. Individual plant species responded differently in the two systems. For example, Antennaria dioica seemed to perform well -in terms of qualityvisual quality -in the Rockwool system, but this was not reflected in the area covered. Achillea millefolia, on the other hand, showed better performance in the pumice-filled pocket system in terms of qualityquality, but this was not reflected in the area covered by the plants. Other species, such as Armeria maritima, did not perform better in either system in terms of qualityquality, but the area covered was higher in

“…The temperature difference at the wall surface between a greened and non-greened facade is approximately 6℃ in a study in Germany. Wong et al founded a maximum reduction of 11.6℃ by a vertical greening wall in Hortpark (Singapore) [2]. Wong et al stated that vertical greenery systems reduced a maximum temperature of 11.5℃ at building facades in tropical climates [25].…”

“…Areas with vertical vegetation are cooler than light-coloured bricks, walls and black surfaces that are typically found in urban areas, because vegetation can alleviate Urban Heat Island (UHI) directly by shading buildings from solar radiation and through evapotranspiration cooling [2,17], reducing solar reflection and re-radiation to atmosphere [2]. The shading effect of vertical greenery systems results in an 8% reduction in annual energy consumption [18].…”

“…Vertical greenery systems (VGS), known as the greening of the facade of building walls [2]. VGS have a positive influence on the comfort and well-being in and around the building [3], can offer numerous ecological and environmental benefits as innovative components of urban design and increase greenery in built environments lacking green areas [4][5], which is still a relatively new discipline and has become one of the most rapidly developing fields in the worlds of ecology, horticulture and the built environment [2]. Many factors affect performance of VGS, such as plants species, substrate type, orientation and dimensions and so on.…”

Abstract. For high-density urban environments, vertical greenery is often employed as one of feasible alternatives of environmental improvement. Vertical greenery systems (VGS) are being served as an interesting measure to improve the quality of life and urban environments, but only a few studies have examined overall performance of VGS. Vertical greenery has potential benefits, including reducing the surface temperature of buildings facades and diurnal temperature fluctuation, alleviating Urban Heat Island and noise pollution, reducing g heat flux to the building and energy cost, transforming the urban landscape and enhancing visual effect and so on. This paper provides a literature review for VGS studying, including VGS classification and their effects on acoustic insulation, thermal, air flow and temperature, energy performance, CO 2 sequestration and microclimatic layer.

“…According to Kohler (2009), less than 5% of all facades in Berlin were grown with plants on the external building wall. In Singapore, Wong (2009) currently experimented on various vertical greenery systems for comparison on which system can reduce wall temperature. Fruits from green facades such as espaliers systems are edible (Kohler, 2009).…”

Researches on biofacade were mainly on project development. Usually plants selections were based on aesthetics, especially plants with flowers or with canopies. However, very little research has been carried out on the practicality of plants on walls. Basically legume plants produce fruits and can be an asset to the building, without sacrificing its aesthetic value. Four species of legume plants in Malaysia were identified and installed as a biofacade wall. An experiment is being undertaken for all the four species on a building wall to investigate growth performance.
